论文摘要
我们分析了一种新的机制，用于在镜像等离子体中创建和限制能量电子。由最终重新定位的相干静电振荡驱动的Fermi-Ulam型工艺，提供轴向加速度，而自然的非可绝化μ会提供相位去相关和能量各向同性化。这种新型的2-D组合导致通过扩散损失模型计算的电子能量分布函数，以假设麦克斯韦形状，而μ非糖性降低损失 - 损失 - 逃脱并消除了较低尺寸模型的绝对级 - 栏限制奇里科夫标准。将理论预测与实验的数据进行比较。
We analyze a new mechanism for the creation and confinement of energetic electrons in a mirror-configuration plasma. A Fermi-Ulam-type process, driven by end-localized coherent electrostatic oscillations, provides axial acceleration while a natural non-adiabaticity of μ provides phase decorrelation and energy isotropization. This novel 2-D combination causes the electron energy distribution function, calculated with a diffusive-loss model, to assume a Maxwellian shape with the μ non-adiabaticity reducing loss-cone escape and annulling the absolute-barrier energy-limiting Chirikov criterion of lower dimensional models. The theoretical predictions are compared with data from an experiment.
